Tips: Isolator Switch Applications:
1. Isolator switch is used to isolate the power supply and disconnect the high-voltage maintenance equipment from the live equipment so that there is an obvious disconnection point between them.
2. Switch off switches and circuit breakers according to the needs of the system operation mode to change the system operation wiring mode.
3. Used to connect or disconnect small current circuits.
Comfortable price isolator switch has the advantages of small size, light weight, long life and low loss. Rated current 100 Amps, can select 3 pole or 4 pole, rated insulation voltage 690V rated, factory direct sales。
